Pompeius and the democrats thus found themselves urged
into coalition. Personal dislikings were probably not wanting
on either side: it was not possible that the victorious general
could love the street orators, nor could these hail with pleasure
as their chief the executioner of Carbo and Brutus; but political
necessity outweighed at least for the moment all moral scruples.

The democrats and Pompeius, however, were not the sole parties
to the league. Marcus Crassus was in a similar situation
with Pompeius. Although a Sullan like the latter, his politics
were quite as in the case of Pompeius preeminently of a personal kind,
and by no means those of the ruling oligarchy; and he too was now
in Italy at the head of a large and victorious army, with which
he had just suppressed the rising of the slaves. He had to choose
whether he would ally himself with the oligarchy against the coalition,
or enter that coalition: he chose the latter, which was doubtless
the safer course.

With his colossal wealth and his influence
on the clubs of the capital he was in any case a valuable
ally; but under the prevailing circumstances it was an incalculable
gain, when the only army, with which the senate could have met
the troops of Pompeius, joined the attacking force. The democrats
moreover, who were probably somewhat uneasy at their alliance
with that too powerful general, were not displeased to see
a counterpoise and perhaps a future rival associated with him
in the person of Marcus Crassus.
